Lighter of multiple torch flames

ABSTRACT

A lighter of multiple torch flames comprises a nozzle and vaporizer assembly that includes a vaporizer, a mixing chamber, and at least two burner nozzle channels generally in V-orientation. The vaporizer has at least one central opening and a filter below the opening, thereby generating a burst of clean vaporized combustible gas to pass through a path toward the burner nozzle channels. The mixing chamber has at least one air inlet where the combustible gas is mixed with fresh air. The nozzle channels have a joint point within a stabilizing chamber of a diameter smaller than that of the path, thereby directing the few combustible gas to diversion channels to form a ring of surrounding flames and most toward the nozzle channels to form at least two forceful and distinct torch flames in straight column shape when being ignited.

FIELD OF THE INVENTION

[0001] The present invention relates generally to a lighter that is commonly used to light cigarette and cigars. More particularly, the lighter of the present invention produces multiple visible flames that are aesthetically pleasing, functional, and wind resistant. But more important it generates flames, each being in a straight torch column shape, rather than drum or water drop shape.

BACKGROUND OF THE INVENTION

[0002] A lighter is a common tool that replaces matches as a source of fire to ignite cigarettes and cigars. The lighter is easier to carry and safer than matches. The lighter is also more aesthetically pleasing. Furthermore, depending on the design, a lighter is generally more wind resistant than a match. Nonetheless, a conventional cigarette lighter may still have various problems, and thus many peoples make effects to improve the cigarette lighters.

[0003] A normal lighter has a housing that defines a fuel reservoir therein, and the fuel reservoir contains a kind of liquid combustible gas. There is a valve assembly that releases the combustible gas from the fuel reservoir into a burner assembly where an igniter, such as the piezoelectric igniter or fire store igniter, may ignite the gaseous combustible gas released from the fuel reservoir. Once ignited, the visible flame can be formed to light cigarettes or cigars. Generally, the lighter flame is a single visible flame that is in the shape of a water droplet. Such a flame is relatively soft, and normally still in red. It can be easily blown away from the object to be lighted or can be even blown out by wind. Most of cheap lighters cannot burn sufficiently the combustible gas to generate a flame of higher temperature. Thus, the conventional single flame is difficult to aim the object to be lighted and difficult to ignite cigars or any objects that cannot be easily ignited.

[0004] Accordingly, many effects have been made to improve cigarette lighters. Some of them are aimed to improve the efficiency of the burner so as to relatively sufficiently burn the released combustible gas to form “blue flame” instead of “red flame.” Some effects are made to provide a wider flame, such as, Japanese Patent Application Laid Open JP10-238773 and U.S. Pat. No. 5,711,662 to Ishiguro. Both of them use two flame burnout holes or two burner nozzle channels arranged side-by-side such that the flames may commingle each other upon exit of the respective flame holes or nozzle channels. The commingled flame (a single flame) may have a width as a divergence for connecting the two holes or nozzle channels. It can be understood that such a wider flame may provide additional heat to ignite cigarettes and wider contact with a cigarette having a thick diameter, such as a cigar. Some of other effects are also made to provide sheltering means or the like to prevent the flame from being blown out. However, these approaches do not really solve all of the problems the cigarette lighters have.

SUMMARY OF THE INVENTION

[0005] A main objective of the present invention is to provide a torch lighter that is constructed to produce two or more forceful diverging torches wherein a torch stabilizing and firming technology is employed in the torch nozzle head to virtually produce a forceful and distinct gathering group of soaring torches, that is especially good at igniting cigars.

[0006] Another objective of the present invention is to provide a torch lighter that can produce a group of diverging torches for providing more heat at higher temperature that makes ignition operation prompt and easy.

[0007] Another objective of the present invention is to provide a torch lighter that is windproof by producing two or more or more forceful and distinct soaring torches.

[0008] Another objective of the present invention is to provide a torch lighter which employs a torch stabilizing and firming arrangement to prevent the forceful soaring torches from directly bursting into the air by providing an annular ring of flame which are united and mixed with a bottom portion of the soaring torches to form a stable surrounding root flame so as to hold the torches from being burst away by the escaping high-pressured fuel and thus gather to form a forceful and distinct group of torches.

[0009] Another objective of the present invention is to provide a torch lighter which virtually produces two or more flows of fuel to generate two or more torches by providing a diversion joint edge between adjacent the lower section of every two elongated nozzle channels.

[0010] In order to accomplish the above objectives, the present invention provides a torch lighter comprising a housing; a fuel reservoir being defined within the housing for containing a liquid combustible gas therein; a valve means for releasing the combustible gas from the fuel reservoir; an ignition means being operable in association with the valve means for lighting the released combustible gas; a vaporizer having at least one central opening serving as an exit of the released combustible gas, thereby generating a burst of vaporized combustible gas, said central opening having a diameter of 0.055-0.15 mm; a filter is provided between the valve means and the central opening of the vaporizer; a mixing chamber of at least one air inlet thereon such that the combustible gas is mixed with fresh air in the mixing chamber; a flame chamber is provided on the top of the mixing chamber; at least two nozzle channels being generally in V-orientation; and a plurality of diversion channels extending from the nozzle body for diverting few amount of the combustible gas into a flame chamber, while most of the combustible gas passes through the nozzle channels to emit upwardly. Thus, the igniter will ignite the combustible gas from the diversion channels before igniting the primary jets of combustible gas out of the nozzle channels so as to form a ring of surrounding flames before to form at least two forceful and distinct torch flames in straight column shape.

[0011] According to the present invention, the diversion channels are extended from a focal point of the V-oriented nozzle channels. The focal point of the V-oriented nozzle channels is upstream of the mixing chamber. The central opening of the vaporizer and the mixing chamber are coaxial to form an exiting path of the combustible gas, and the V-oriented nozzle channels are symmetric with respect to the exiting path. The diameter of each nozzle is 0.5-1.5 mm. A part of the connecting portion between the nozzle block and the vaporizer is rotatable with respect to the axial of vaporizer. A stabilizing chamber is provided in the base of the nozzle block, thereby directing most of the combustible gas toward the burning nozzle channels and few toward the diversion channels.

[0012] Alternatively, the diversion channels may be provided adjacent to the top of each nozzle channel, while the nozzle outlet is narrower than the nozzle channel leading from the exiting path of the combustible gas. However, the manufacture of such diversion channels is more complicated and costly than V-oriented nozzle channels of the diversion channels at the base. Such diversion channels also require more accurate machining.

[0013] The lighter of the present invention may generate multiple flames, each being in a straight torch column shape. Such a flame has a higher temperature at its tip because the bursting flame has most of heat concentrated on the tip. Along the exiting path, the combustible gas released from the central opening of the vaporizer may have a sufficient mix with fresh air in the mixing chamber and will encounter a small proper resistance at the branching joint point of V-oriented nozzle channels such that most of the bursting combustible gas passes through the nozzle channels to emit upwardly, while few amount of the combustible gas is diverted from the branching joint point of the nozzle channels and goes through the diversion channels.

[0014] The primary jets of flames out of the nozzle outlets will not commingle with each other because they come out of the nozzle outlets forcefully, and they cannot be easily blown away or blown out by wind. The surrounding flames generated from the combustible gas coming out of the diversion channels may serve a support to the primary jets of flames, and may maintain the jets of flames provided that a strong blow of wind sweeps off the primary flame jets instantaneously.

[0015] The present invention can be better understood from the accompanying drawings and the detailed description thereof.

DETAILED DESCRIPTION OF THE INVENTION

[0033] Referring to FIG. 1, the preferred embodiment of the present invention comprises a housing 1 that defines a fuel reservoir 21, an ignition mean 3 being attached to the housing 1, a valve assembly 22 disposed within the fuel reservoir 21 for releasing the combustible gas from the reservoir 21, a vaporizer and mixing assembly, and a burner nozzle assembly. The valve assembly 22 has a valve 23 and an actuation lever 5. This actuation lever 5 is pivotally connected to the valve 23 and incorporated with the ignition mean 3. A connection tube 6 connects the valve 23 to the vaporizer and mixing assembly.

[0034] As seen in FIG. 2, the adjustable valve 23 may open and close a central opening 410 of the vaporizer 41. The central opening is 0.055-0.15 mm. Below the central opening 410 is a filter 411 that is used to clean up unwanted impurities blocking the central opening. At the upstream of the vaporizer opening 410, a mixing chamber 42 is provided approximately coaxial with the central opening 410 and has at least one air inlet 421. A throat conduit 422 is connected to the mixing chamber 42 and leads to the burner nozzle assembly. The connecting throat conduit 422 is of a diameter of 1.0-2.5 mm. The burner nozzle assembly includes a nozzle block 43, and a flame chamber 44. The nozzle block 43 is attached on the top of the throat conduit 422 at upstream of the mixing chamber 42, and has at least two nozzle channels 431 in V-orientation. The nozzle channel is about 0.5-1.5 mm in diameter. The ignition means 3 may light the combustible gas in the flame chamber 44. The nozzle block 43 is within the flame chamber 44 and they are together disposed in the upper portion of the housing 1.

[0035] By depressing the button of the ignition mean 3, it will also activate the actuation lever 5 of the valve assembly 22 such that the combustible gas is released from the fuel reservoir 21 and passes through the connection tube 6, entering into the vaporizer 41 wherein the fuel is vaporized through the central opening 410. The vaporized combustible gas enters into the mixing chamber 42 wherein the vaporized fuel is mixed with fresh air provided through the air inlets 421, and then passes through the throat conduit 422 to reach the nozzle block 43. The vaporizer opening 41, mixing chamber 42, and throat conduit 422 form an exiting path of the combustible gas before the nozzle body 43.

[0036] The nozzle channels 431 in V-orientation have a joint point or focal point located at upstream of the throat conduit 422, that is on the axis of the exiting path of combustible gas. The joint of the V-oriented nozzle channels 431 has a small surface area 433 facing the throat conduit or mixing chamber, and the surface 433 is designed to be so small that has a minimum resistance to the out-going combustible gas such that most of the combustible gas goes into the nozzle channels 431, while few amount of the combustible gas are diverted at the joint of the V-oriented nozzle channels 431 and goes through the diversion channels 4311.

[0037] As seen in FIG. 2, the diversion channels 4311 are cylindrical and perpendicular to the axis of the exiting path. The channels extend from the focal point of the V-oriented nozzle channels 431 and lead the few amount of combustible gas to form a ring of surrounding flames when the combustible gas is ignited. Each diversion channel 4311 has a round cross section or is a hole. There is a hollow space 45 between the focal point and the top of the throat conduit 422. Thus, the combustible gas out of the V-oriented nozzle channels will generate at least two forceful and distinct torch flames in straight torch column shape as seen in FIG. 2.

[0038] As shown in FIG. 2, the ignition means is provided at a side of the nozzle block 43 and above but a bit further off the passage of the combustible gas coming out of the diversion channels. Thus, the igniter will ignite the combustible gas from the diversion channels before igniting the primary jets of combustible gas out of the nozzle channels 431. Now referring to FIG. 3, it shows a cross-sectional view of another preferred embodiment of the vaporizer, mixing chamber, and three nozzles of the present invention. The three nozzle channels 4311 are arranged with the two side nozzle channels in V-orientation and the central nozzle channels in the axis of the exiting path of the combustion gas. The small surface areas 433A between the nozzle channels are so small that will only have a minimum resistance to the out-going gas to let most of the combustible gas passes through the nozzle channels to emit upwardly. The area is 1.0 mm. The diversion channels 4311 are in the same arrangement of those of FIG. 2.

[0039] The difficulty of forming three torch flames in straight column shape is that the flames tend to commingle with each other because they are so closely located. Thus, it can be understood that the provision of the vaporizer 41 and mixing chamber 42 as well as the throat conduit 422 assures that the flames will not commingle in association with the diversion channels 4311 and the generally V-oriented burner nozzle channels 431. It not only assures the forceful out-going combustible gas, but also assures the sufficient burning of the gas. Therefore, the primary jets of flames from the nozzle channels may generate higher temperature at the tip of flames.

[0040]FIG. 4 shows another embodiment of the vaporizer, mixing chamber, and two V-oriented nozzle channels of the present invention, having the diversion channels 4311A adjacent to the top of each nozzle channels. In this arrangement, the outlet 432 of the nozzle channels 431 must be narrower and the diversion channels 4311A must be near the outlet 432 such that the ring of surrounding flames may assist and stabilize the forceful and distinct torch flames.

[0041]FIG. 5 is a perspective view showing the vaporizer and nozzle assembly of the preferred embodiment of FIGS. 1 and 2, but the nozzles have a gear type outer profile. As seen in FIG. 5, the burner block 43 has surrounding vertical diversion channels 4311B that lead the few amount of diverting combustible gas out in the axial direction of the exiting path of the combustible gas. This will assure a better ring of surrounding flames. Such a nozzle block 43 sits inside a seat of the vaporizer and mixing assembly and fits therewith such that the vertical wall of the seat defines the surrounding channels 4311B together with the channeled profile of the nozzle block 43.

[0042]FIG. 6 shows the gear type nozzle block of FIG. 5. It shows the channeled outer surface of the nozzle block 43. The surrounding channels 4311B are uniformly formed. As further seen in FIG. 7, the bottom portion of the diversion channels are now actually a layer of space 451 defined by the top surface of the vaporizer and mixing assembly and the bottom surface of the nozzle block 43. However, the layer of space 451 functions actually as multiple diversion channels 4311 extending from the focal point of the V-oriented nozzle channels 431. Each of such virtual diversion channels 4311 has a corresponding surrounding channel 4311B. The space 451 substitutes the multiple diversion channels 4311 and eases machining of the parts. As seen in FIG. 7, the joint area 433 is 1.0 mm. It can be understood that the igniter positioned properly above the surrounding combustible gas channels will ignite accurately the ring of surrounding gas before igniting the primary jets of combustible gas.

[0043]FIG. 8 is a perspective view showing the vaporizer and nozzle assembly of the preferred embodiment of FIG. 3 having three nozzle channels, but the nozzle body have a gear type outer profile. Similar to FIG. 5, the gear type nozzle assembly sits inside the seat at the top of the vaporizer and mixing assembly, and fits therewith such that a plurality of vertical diversion channels 4311B are defined between the vertical wall of the seat and the channeled outer profile of the nozzle block 43.

[0044]FIG. 9 shows channeled outer surface of the gear type nozzle block of the present invention of FIG. 8, and FIG. 10 shows that the diversion channels 4311 are now a layer of space 451 extending at the plane of the focal point of the basically V-oriented nozzle channels 431. The gear type nozzle block is for easy manufacture, and may also assure the uniform ring of surrounding flames.

[0045] In an alternative embodiment of FIG. 11, the diversion channels are not in round cross section or holes, but slots 4311C. These slots 4311C are provided at the bottom of the V-oriented nozzle channels 431. The downward slots 4311C substitute the hollow space 45 as shown in FIGS. 2 and 3.

[0046]FIG. 12 shows an alternative embodiment of the nozzle body. The nozzle channels 431 are first in V-orientation and then have an upper part of parallel nozzle channels 431A. FIG. 13 shows a further embodiment of the nozzles configuration that is similar to FIG. 12, but has the diversion channels 4311A adjacent to the top of the nozzle channels 431. The outlet 432 of the nozzle channels 431 is narrower than the nozzle channels, a stabilizing chamber is being provided between nozzle channels 431 and diversion channels 4311.

[0047]FIG. 14 shows a modified embodiment of the present invention, a stabilizing chamber 451 has a smaller diameter that is less than that of the throat conduit 422. The vaporizer 41 is provided within an internal sleeve 60, in which the ring-shaped piece of the vaporizer 41 and the mesh filter 411 are fitted. Thus, the connecting portion, that defines the mixing chamber and throat conduit, has a outer sleeve 61 sliding onto the internal sleeve 60 of the vaporizer 41 and being adjustable to rotate with respect to the vaporizer 41. Such rotation is aimed to adjust the central opening of the vaporizer to be precisely co-axial with the focal point of the V-oriented burning nozzle channels so as to enable the uniformity of the primary at least two multiple bursts. The stabilizing chamber 451 functions to direct the combustible gas to generate the basically V-oriented nozzle channels 431. The gear type nozzle block is easy for manufacture, and may also assure the uniform ring of surrounding flames.

[0048]FIG. 15 illustrates an alternative embodiment of the vaporizer, the filter and the valve means. The vaporizer 41 is mounted within the connecting portion, while the filter 411 is fitted on top of the valve means 23. The vaporizer 41 is connected to the filter portion through a soft rubber connection 24. A stabilizing chamber 451 has a diameter equal to the conduit throat 422.

[0049]FIG. 16 shows a further modified embodiment, in which the connecting portion defining the mixing chamber and throat conduit is of two parts. The upper part is fitted with the burning nozzle block and the lower part is screwed into the upperpart such that the vaporizer mounted within the lower part can be adjusted to have the central opening in line with the center or focal point of the burning nozzle channels. Here again provided is a stabilizing chamber 451. The advantages of the adjustable vaporizer is aimed to adjust the central opening of the vaporizer to be precisely coaxial with the focal point of the V-oriented burning nozzle channels so as to enable the uniformity to the primary at least two multiple bursts.

[0050]FIG. 17 shows that the nozzle block and flame chamber 44A can be in a oval shape when there are three nozzle channels provided. This creates better space between the outlets of the burning nozzle channels, and reduces the thickness of the lighter.
